ber 25, 1922, (now Patent No. 1,824,248, issued September 22, 1931) ofwhich this is a division.

An object of this invention is the provision of means for operating amachine of the key-operated type from a source of power other than akey. 7 I

Another object of the invention of this application is the provision ofmechanism for operating a universal key detent by depression of eitherof two machine releasing keys which connect either the item entering anditem printing mechanism or the total printing mechanism to the source ofpower.

Another object of this invention is the provision of means for lookingout the total key by a partial operation of the universal key detentupon depression of an amount key.

With these and incidental objects in view, the

invention consists in certain novel features of construction andcombinations of parts the essential elements of which are set forth inappended claims and a preferred form of embodiment of which ishereinafter described with ref- ,erence to the drawings which accompanyand form part of this specification.

In said drawings:-

Figs. 1A and 13 comprise a plan view of the machine with parts omitted.

Fig. 2 is a transverse section through the machine looking toward theright.

Fig. 3 is a detail view showing the mechanism for releasing the motorand driving the key coupler during item entering operations.

Fig. 4 is a detail view showing the mechanism for releasing the machineand driving the printer during total-taking operations. 7

The machine comprises a plurality of groups of amount keys, attotalizer, item entering and item printing mechanism, total printingmechanism, driving means, and keys for connecting the driving means witheither the item entering and item printing mechanism or the totalprinting mechanism. The printing mechanisms are not disclosed in thisapplication.

The keyboard comprises a plurality of groups or amount keys (Figs. 1A,1B and 2) and item control key 21 (Figs. 1A and 3) and a total controlkey 22 (Figs. 13 and4). The amount keys 20 "comprise, two members, afront manipulative member 23, and a rear member 24 adapted to be Bothmembers are pivoted upon a rod 19 mounted in the side frames of themachine. The item control and total control keys are mounted upon theends of the rod 19 projecting through said side frames.

In machines of this type, the members 23 and 24' generally heretoforehave been integral to drive the key coupler by depressing the keys. Inthis machine, the manipulative member 23, is depressed only a slightextent, and this slight movement thereof functions'to stretch a spring25 (Fig. 2) secured to the frame and to a lever 26 pivoted to saidmember and provided with a pin 27 projecting over said member and inengagement therewith, into the plane of a forward extension 28 of themember 24.

After a manipulative member is depressed, spring pressure will beexerted on the extension 28 of its corresponding rear key member to urgethe rear end thereof toward the key coupler. As the key coupler israised, the rear key member is also raised independently of the frontkey member 23 by the spring 25 a suficient distance to effect a Icoupling connection with the key coupler.

Uprights 34, connected to the rear ends of the rear key members, areprovided with notches for engaging rods 36 carried by rocker memberscontrolling totalizer actuators 37, the notches being located totransmit amounts of movement to the actuators proportionate to thenumber of units represented by the appropriate keys. The actuators 37and their respective rocker members are operatively connected together.

The totalizer actuators are normally in mesh with gears 38 which areconnected with the item printing wheels (not shown) to set up theamounts represented by the keys depressed.

The right hand end of the key coupler is provided with a trunnion 56extending through the printer frame.

The amounts represented are also entered in a totalizer mounted in aframe 66 (Fig. 2) pivotally supported in brackets projecting rearwardlyfrom a front cross member 68 and secured'to the side frames. Thetotalizer is in all respects the same as that shown in the Von Peinpatent referred to.

The amount accumulated on the totalizer is ascertained by a printingoperation. For this purpose mechanism is provided for setting up totaltype wheels (not shown) in accordance with the amount in the totalizer,This mechanism comprises stepped disks 86 rigid with gear wheels 8'7meshing with the gears '71 rigid with the totalizer pinions, and feelers96, all constructed by the keys depressed and operating as in the VonPein patent referred to.

The driving means preferably comprises a motor of the usual type (notshown) which drives a clutch shaft 151 (Fig. 4). Mounted on the innerend of this shaft 151, is a gear 152 (Figs. 1B and 4) in mesh with agear 153 secured to a shaft 154 supported in the main right hand frame155 and a bracket 156 secured to the motor casting.

Freely mounted on the shaft 154 is a cam disk 160 which cooperates witha roller 161 (Fig. 3) on a pivoted arm 162 connected by a link 163 withan arm 164 secured to the key coupler trunnion 56. The cam disk isprovided with a female clutch member 165. Also freely mounted on theshaft 154 is a gear 166 (Fig. 1B) in mesh with a gear 167 secured to thetotal printing drive shaft 108. The gear 166 is provided with a femaleclutch member 168.

The means for causing the cam disk 160 and gear 166 to rotate with theshaft 154 comprises the female clutch members on the disk and gear and asleeve clutch member 169 (Figs. 1B and 4) slidably, but non-rotatably,mounted on the shaft 154 and provided with male clutch end portions tocouple with either of said female clutch members.

Normally the sleeve clutch member is held in engagement with the clutchmember by means later referred to. In this position, it drives the keycoupler for an itemizing operation. When it is desired to print a totalaccumulated on the totalizer, the sleeve clutch member is moved to theright into engagement with the clutch member 168. This is effected bythe total key 22, which will be described later.

Interlocking and control features When the amount key members 23 aredepressed, they set up a spring pressure against the rear key members 24to select them for operation. The key members 23 are held depressedtemporarily by spring-controlled angle plates 170 (Figs. 1A, 1B and 2)which snap over projections 171 thereon. There is one plate 170 for eachgroup of keys. These plates are supported by arms of levers 172rotatably mounted on a rock shaft 173. The lower ends of these leversbear against pins carried by arms 174 pinned to the rock shaft 173. Theplates 170 are normally held in the position shown by springs secured tothe lower ends of levers 172 and to a rod carried by the frame of themachine. The shaft 173 extends through the right hand side frame whereit is provided with an arm 175 (Fig. 3) controlled by a lever 176 freelymounted on a control shaft 180, later referred to. By means of the lever176, depressed keys may be released before an entry of items is eifectedto make corrections in the amount set up.

A look lever 184 (Fig. 4) releases the motor when movedcounter-clockwise by a spring 185 and arrests the motor when movedclockwise by an arm 186 rotatable with the shaft 154.

The spring 185 is connected to the frame and to a slidably mounted link187connected to the arm 184. The link 187 is normally held in theposition shown in Fig. 4 by a spring-actuated laterally directed fin 194in alignment with the lip 191. This catch member is also provided with ashoulder to cooperate with the stud 189. When the catch member 192 ismoved downwardly, the catch 188 is released and the lock lever 184 ismoved to releasing position. When the lock lever is returned to lockingposition, the parts move back to the position shown in Fig. 4. A tensionspring 196 holds the catch against the stud 189.

The releasing mechanism described may be controlled from either the itemcontrol key 21 or the total control key 22. The control shaft 180 ismounted in the side frames of the machine. Adjacent to its left end itcarries a rigidly fixed arm 200 (Fig. 3) provided with a pin 201extending under a bearing edge 202 on the item control key. The key andarm 200 are held in home position by springs 203 and 204.

Secured to the shaft 180 adjacent to the right hand side frame of themachine, is an arm 205 (Fig. 4) which carries a pin 206 projectingthrough a plate 207 pivoted on the catch memher 192 at 208 and slottedas shown, to receive the stud 193 on which the catch member 192 issupported. The total control key 22 (Fig. 4) carries a pin 209 forengagement with the plate 207 from which it is spaced when in its homeposition. The key 22 is normally held in home position by a spring 210connected to a long stud 211 on the key and to the frame.

When the item control key or total control key is depressed, the controlline 180 is rocked to move the catch member 192 downwardlyto release themotor. When the motor releasing mechanism is returned to home position,the springs 204 and 210 return the control line and total key to homeposition.

The clutch sleeve 169, before described (Figs. 1B and 4), is normallycontrolled from the total control key 22, which isnormally held in homeposition by the spring 210. The key is provided with an arm 215connected by a link 216 with an extension 217 on a yoke 218 whose sidemembers are mounted for rocking movement on the sleeve clutch member169. The yoke 218 is held thereon by a sleeve 219 located between theside members of the yoke and connected to the sleeve clutch member byany suitable means 220. The base of the yoke 218 is convex and isprovided with a cam groove 221 cooperating with a fixed stud 222 carriedby the frame of the machine. By means of the mechanism described, thesleeve clutch member 169 is normally connected with the key couplerdriving clutch member 165, and

upon depression of the total control key, is moved into engagement withthe clutch member 168 for the total printing mechanism.

It is desirable to prevent an operation of the total control key afteran item entering operation has been begun by the depression of an amountkey. For this purpose, the amount keys are provided with cam portions230 (Fig. 2) which cooperate with a universal locking member 231supported by arms 232 secured to the control shaft 180.

When an amount key is depressed, the control shaft 180 and pin 206 (Fig.4) are rocked in a clockwise direction a sunicient distance to swing theupper end of a pawl 233 under the stud 211 on the total control key. Theamount key is held in this position by the temporary locking plate 170(Fig. 2). This rocking movement of the shaft 180 is not sufficient torelease the machine for operation, such release being subsequentlyeffected by the depression of the item control key 21.

When the item control key 21 is depressed, the control shaft 180 isrocked from the position to which it is set by the depression of anamount key 20, to carry the locking plate 231 over projections 240 (Fig.2) of amount keys depressed and under projections 240 of amount keys notdepressed, and releases the motor for an item entering operation. It isnecessary to provide the release key 21 to release the machine, insteadof depending upon the depression of an amount key 20 to rock the shaft180 a suflicient distance to efiect such release, since if thedepression of any amount key 20 were to rock the shaft 180 far enough torelease the machine, the flange 231 would be rocked beneath theprojections 240 of all the undepressed keys 20. Then, it would beimpossible to depress another amount key to complete the entry of anamount of more than one digit. Rocking the shaft only slightly by theamount keys 20 locks out the total control key, in the mannerhereinbefore described, and after all the amount keys 20 have beendepressed, the item control key 21 is depressed to release the machine.When the motor releasing mechanism is returned to home position, thepawl 233 is returned to home position by a spring 241 connected theretoand to the total control key 22.

The total control key may be depressed after an item operation iscompleted or at any time when no amount keys are depressed. When thetotal control key is depressed, it first connects the sleeve clutchmember 169 with the clutch member 168 to drive the total printingmechanism. The control line 180 is then rocked to lock out all of theamount keys. This movement of the control line rocks the pawl 233 overthe stud 211 carried by the total control lever holding the leverdepressed until the total printing operation is completed. When thisoperation is completed, the total control lever will be released, andthe clutch sleeve member 169 will be returned to home position by thespring 210.

The key members 23 are also provided with portions 250 for cooperationwith plates 251 pivoted on a cross frame member 252 to prevent asimultaneous depression of a plurality of amount keys in the samedenominational group.

Operation An item of a transaction is entered in a totalizer and printedon an issuing strip by first depressing amount keys representing theitem and then subsequently depressing the item control key. After eachof the items of a transaction has been entered and printed, the totalcontrol key is depressed to operate the total printing mechanism, whichprints the total of the items involved below the items, feeds theprinted total past a severing knife, and clears the totalizer to prepareit for a subsequent transaction.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form orembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
